Small flycatcher with a short bill and a long slender tail. Found in the canopy of humid forests. Olive above and yellow below, with a white eyebrow, pale face, pale base to the lower mandible, and two broad prominent pale wingbars. Very similar to Reiser’s Tyrannulet, but is slightly bigger with a paler face. The song is a sharp nervous series of “briu-briu-briu” notes.
